Singh was referring to the black chapter of UP and Mayawati's history when in 1995 the BSP chief was forced to stay in the VVIP guest house by Samajwadi Party goons after she pulled out of the ruling alliance with their party.

Former Samajwadi Party leader Amar Singh on Thursday claimed that Bahujan Samaj Party (BSP) chief Mayawati will never forget the infamous guest house incident and will thus never agree to forge an alliance with the Samajwadi Party.

Singh was referring to the horrific incident in Mayawati's history when in 1995 the BSP chief was forced to stay in the VVIP guest house by Samajwadi Party goons after she pulled out of the ruling alliance with their party.

In the past 23 years, Mayawati never considered an alliance with SP, until the recent Lok Sabha bypolls, when she backed SP candidates in Gorakhpur and Phulpur to present a strong front against BJP in its bastion.

The unlikely alliance paid off, giving birth to speculations that the two parties might come together for 2019 general elections as well.

Akhilesh Yadav's one-to-one meeting with Mayawati at her residence last night added fuel to the rumours. It was first time in 23 years that she met anyone from the Yadav family.

Discrediting the rumours, veteran politician Amar Singh claimed that the BSP chief will never agree to an alliance with SP unless Mulayam Singh Yadav is sent to jail.

"Mayawati can never forget 'guest house incident'. Akhilesh can perhaps make a compromise with Mayawati by agreeing to send his father (Mulayam Singh Yadav) to jail," Singh told media on Thursday.

Mulayam Singh, however, claimed that the past was in the past and both parties have moved on.

"We are not saints, we are here for power. Guest house incident is in the past, we have moved on. We have been with Mayawati before," Mulayam Singh said.

Still in shock, over the success of BSP-SP alliance in UP bypolls, ruling government's ally Apna Dal leader Anupriya Patel alleged that BSP chief Mayawati was willing to forget the 'guest house incident' now as she was scared after the election loss.

"Mayawati is ready to forget 'guest house incident' as she is scared after the election loss. But bypolls, will not have any effect on 2019 Lok Sabha elections as PM Modi's work will drive the party's victory," Patel said.
